Don't worry guys - he won't be able to stay away from the Rotary for long!! We'll hear from it/him soon!

Hey, I'm trying to resist :-)

I verified again that the engine doesn't have any of these vibration issues without a prop. The only problem is being rough at low rpm, which is expected with no flywheel, and a single rotor. By a couple thousand rpm, it's plenty smooth.

I also got a chance to try the IVO prop today, and it made a difference, but isn't close to being OK. The flexible IVO tends to make it harder to pinpoint exact rpm's of the problems, but they are still there. In general, the rpm for all the previous problems is 300-500 lower with the IVO, than the Warp Drive. The oscillation in the prop tips is still there, but not as severe as with the Warp Drive.

At this point, I just haven't decided what to do next. If I'm smart, I'll just pull the prop, so the engine runs well, and I'll run it every now and then when I go to the airport. That will keep it healthy, and let me work on the RV-8 instead.
